About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-40
This is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A 100 mm bore delivers 3927 N push and 3769.9 N pull at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa, so it can lift about 200 kg vertically when you keep a 2:1 margin on the 400 kgf theoretical lift. The -40 code sets a 40 mm adjustment window: an external stop screw trims the 120 mm extend stroke anywhere down to 80 mm on site, no disassembly needed.
The hard-anodized aluminium body with an S45C hard-chrome plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a 1.5 MPa (215 psi) proof rating and 30-500 mm/s speed. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the ISO 21287 face. A fixed TPU bumper at each end absorbs end-of-stroke shock. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it never holds a load.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3770 N |
| 0.7 MPa | 5498 N | 5278 N |
| Max (@1.0 MPa) | 801 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-40 Is Used
Press-frame ejector
Ejects formed aluminium castings from a die, with the 40 mm window letting one cylinder serve dies that need 80 to 120 mm of ejection travel.
Pallet gate actuator
Swings heavy safety gates on a warehouse palletising line, where the 3927 N push at 0.5 MPa overcomes gate mass and hinge friction.
Lift-and-locate fixture
Raises a 180 kg steel weldment about 40 mm for locating pins in a machining cell, staying inside the 200 kg vertical-lift guideline.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-40 the Right Cylinder?
Size against the load: at 0.5 MPa the 100 mm bore pushes 3927 N, the 80 mm bore manages 2513.3 N and the 125 mm bore reaches 6135.9 N, so step down to 80 for lighter clamping or up to 125 when you need the extra margin. Plan real work at roughly 2356 N (about 240 kgf) rather than the full rating. Choose the female M12x1.75 rod thread shown here or add B for a male thread, pick FA or LB mounting to suit the fixture, and order the -S code if you later want CMSE / DMSE switches, since without it there is no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-40 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window: an external stop screw shortens the 120 mm extend stroke down to 80 mm. It is a mechanical end stop, not a load lock, so the piston still drifts if air is lost.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA or LB mounting on the standard face. Sensing needs the optional -S magnet: order ACEJ100X120-40S and CMSE or DMSE switches can ride the body slots; the version without -S carries no magnet.
